“野人”被称为世界四大怪之一。我们用PIXE技术测定了5份“野人”毛发、10份灵长类或其他野生动物毛发和9份人发,并用模式识别法对这三类毛发作了鉴定和分类。对数据的统计分析表明,“野人”毛发中的所测元素含量均显著高于动物毛发和人发,而动物毛发中的元素含量不全高于人发。这三类毛发的非线性映照图清楚地指明,“野人”、动物和人都各有他们自己的元素谱特征。 “Savage” is called one of the four big strangers in the world. We measured five copies of “savage” hair, 10 primate or other wildlife hairs and nine human hair using the PIXE technique and identified and categorized these three types of hair using pattern recognition. The statistical analysis of the data shows that the content of the measured elements in the “savage” hair is significantly higher than that of animal hair and human hair, while the content of the element in animal hair is not higher than that of human hair. The nonlinear mapping of the three types of hairs clearly indicates that “savages,” animals, and people each have their own elemental spectrum features.
